Calculator inputs stay in the page
The calculator code processes numbers in your browser memory. This publication does not submit those inputs to an application server, save them in a database, or include them in page URLs. Resetting or leaving the page clears the scenario from the page. Browser features such as autofill may operate independently.
No advertising or visitor analytics added
This release adds no advertising pixels, visitor analytics, third-party fonts, or embedded social widgets. Images, styles and scripts are served with the site. The hosting and domain providers may still process ordinary request information, including IP addresses and security logs, under their own policies.
Search and external sources
Site search filters content already delivered to your browser. Opening Cornell LII, IRS, eCFR, FTB or another external link takes you to an independent site with its own privacy practices. External links open in a new tab and use noreferrer.
Email is correspondence, not intake
The email link opens your mail application. Anything you choose to send passes through email providers and may be retained in the recipient’s mailbox. Do not include confidential taxpayer information. This site has no document-upload or client-intake feature.
